This gives polynomial deformations of the restricted envelopping algebra of the Witt algebra. By this way, we get new families of noncommutative noncocommutative Hopf algebras of dimension p^p in char p.5 pagesQuantum AlgebraRings and Algebras16W30; 17B37; 17B62; 17B66Quantizations of the Witt algebra and of simple Lie algebras in characteristic ptext
